data.europa.eu is the official portal for European open data, operated by the Publications Office of the European Union. It federates roughly 1.9 million dataset records from EU institutions, the national open data portals of the member states and international organisations, and republishes them as DCAT-AP metadata. Six machine-readable APIs sit on top of that corpus: a hub-search metadata search service, a hub-repo DCAT-AP registry for publishers, a Virtuoso SPARQL endpoint, and the Metadata Quality Assurance metrics cache, metrics reporter and SHACL validation services. Read access is public and unauthenticated; publishing into a catalogue requires an EU Login account or a service account issued by the portal team.
EU Open Data Portal publishes 6 APIs on the APIs.io network, including Search API (hub-search), Registry API (hub-repo), MQA Metrics Cache API, and 3 more. Tagged areas include Government, Open Data, SPARQL, EU, and Regulatory.
The EU Open Data Portal catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
EU Open Data Portal’s developer surface includes developer portal, documentation, API reference, getting-started guide, support, engineering blog, authentication, and 25 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Government & Public Sector regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
